blackburn was atrocious and a big reason we got gashed in the running game

."Blackburn is many things: a nice guy, a solid special teams player, and an adequate backup. However he is not a starting linebacker by any measure and failed miserably in that role in 2012. Blackburn graded out at -10.9 overall according to PFF. He had a nightmarish -7.1 grade against the run and allowed 13.8 yards per reception in coverage. He was one of the main culprits for a defense that ranked near the bottom of the league in both run (25th) and pass (31st) defense."
